BERTALN SZAB, OF NE'vV YORK, N. Y., ASSIGN'OR TO A. JOHNSON, OFBROOKLYN, NEW YORK.

FEEDING- ATTACHMENT FOR MACHINES FOR MANUFACTURING BOTTLE-CLOSURES.

Application filed March 9, 1915, Serial NO. 13,246.

Be it known that l, BERTALAN SZAB, a subject ot the King ot Hungary anda resident ot' the city oit New York, in the count \Y ot King.' andState of New York,

have invented certain new and useful lmprorcnnaits in FeedingAttachments tor ii achines tol- Manut'acturing BottleClo sui-es, ot'which the following is a specification.

The present invention relates to an attachment to machines formanufacturing closures tor bottles, cans and the like, including thosetermed crown corks.

lviore particularly the invention relates bling means.;

llcrctot'ore there has been devised feeding means which causes disks topass `from a mass in a hopper to thi` inlet of the tube mentioned, but,as tar as known, no automatic means has been provided which pre ventsclogging ot the inlet. or which causes the disks to be properly stackedin the tube.

(lne ot the objects ot the present invention is to provide a simple andetlicient Jfeeding' attaclnnent which automaticalhr delivers sealingdisks t'rom a mass to a tube. leading' to the assembling machine. saidmeans preventing a clogging' ot the inlet to the tube and causing thcdisks to occupy horizontal positions within thc said tube.

lilith these and otlarohjmts in view, which will more inliv appear asthe nature ot the invention is better understood, the same consists inthc combination. arrangement and construction ot' parts hereinafteriullv described, pointed out in the appended claims and illustrated inthe accompanying' drawings. it being' understood that many changes maylie made in the sin and proportion fot the several parts and details ot'construction within the scope ofthe appended claims without departing'trom the spirit or sacrificing any ot' the advantages of the invention.f

Specification of Letters Patent.

Renewed June 16, 1916. Serial No. 104,098.

One of the many possible embodiments of the invention is illustrated inthe accompanying drawings, in which Figure 1 is a central verticalsection tali'en through a feeding attachment constructed .inaccordancewith the present invention; Fig. Q is a section taken on line 2&2 ot'Fig'. 1; Fig. 3 is a section taken on line 3-3 ot' Fig. 2; Fig. l is avertical section taken through the means for causing a proper initialiilling of the tube leading to the assembling machine; and Fig. 5 is arear elevation ot' the detail shown in Fig. l.

ln the drawings, the numeral indicates a rectangular hopper, into whichare placed the sealing disks for snpplyingthe as* semhling machine, saidhopper being' arranged above the trame or table ot the machine andsupported by any suitable means (not shown). This hopper comprises, forreasons well known, slanting sides 11 and a bottom 12, the latterconsisting' ot two sections 12.) and 14, which slope toward thelongitudinal center line thereof, in which is Jformed in saidl bottom agroove 15 otv considerable depth. The groove runs horizontallythroughout the length of the .bottom, and is formed by vertical sioes 1Gand V17. and a horizontal bottom 1S. The entii'e,st1'ucture is placedupon a boxlike casing 19, the ends 2Q ot which torni at the same timethe endsot' the bottom 12 and its groove. Adjacent to the sides 16 and17 of the groove 15 are Ytermed in thel ends 20 of the box-like casing19 registering rectangular apertures Q1 and 22, said aperturesbeing inalinement with openings -23 and 24 in guide blocks and 2G. respectively,the latter lbeing` attached in any `suitable inannell to the outersurface ot the casing 19. Through these apertures and openings extendtwo Yfiat bars 27 and 2S, onen of' said bars abutting against the side16 of the groove 15, and the other one against the side 17 thereof. Theheight o cach ot these bars is the same as that ot' the groove 15. Thebars are reciprocably disposed in the groove, their movement being'guided by the blocks 25 and QG above mentioned. The bar Q7 is pivoted tothe strap Q9 ot an eccentric 30, and the har 28 to the'strap 31 ol aneccentric 32. The two cci-entries are keyed, or'otherwise tixedlyattached, to a driving shaft 33, the latter being rotatabiy journaled inthe sides 19 of the casing 19. The eccentrics and 32 are staggered 1300,whereby, obviously, the bars 27 and 28 are caused to move always inopposite directions. Rotation is imparted to the driving shaft 33 by abelt (not siurw'n)` running over a pulley 34, that is keyed to thedriving shaft, the belt receiving motion from any suitable means. To theupper facesl of the bars 27 and 28 are attached upwardly projectingagitating arms and to their inner faces teeth or projections 35, for apurpose hereinafter' to be described.

The disks are advanced within the groove 15 in a manner hereinafter tobe described toward the front end of the casing 19, and drop therethrough a discharge opening 37 in the bottom of the groove into aninclined reciprocating tubular member 38, that is provided with "a slot39, extending throughout the length of its upper portion, and being of awidth immediately below the opening 37 that is somewhat greater than thediameter of a sealing disk, said width decreasing toward the outlet ofthe member 3S. Tlf` inner diameter of the tubular member 33 is "reaterthan the diameter of a sea u diC t The tubular member 38 is reciprocatedin a guide 40, that is secured to the casing if) in alinement with anaperture :s-1 in one of the sides 19 of said casing. The rear end of thetubular member 38 is closed by 'a head that is connected by means of apituian 1-3 with a Ycrank eti, ,1e latter being keyed to a shaft 45,vthat is stably mounted in a bearing 46 and in one of the ends 2O of thecasing 19. Rotation is imparted to the shaft from the main driving shaft33, for instance there is fastened 'to the shaft i5 a worm 47 in meshwith a worin gear 4S, the latter being attached to the shaft With theaperture 41 communicates a tubular fitting L19, the longitudinal axis ofsaid iitting coinciding with that of the tubular reciprocating member33. From the fitting e9 leads a tube 50 to the transporting means uponthe assembling machine, which conveys the sealing disks, one after theother, to the assembling means. The upper portion of this tube iscurved. its lower portion being substantially vertical. ln the curvedportion of the tube is formed a slot 51. Through thisI slot is adaptedto projectinto the tube a linger 52 of a weighted lever 53, athe saidlever being pivoted at 5i to aring 55, that embraces the tube 50. Theweighted end ofthe `lever 53 is connected by a iexible connection 5Gwith some stationary part of the hopper.

The operation of this device is as follows: A mass of sealing disks isplaced into the hopper. and rotation is imparted by the intermediary ofthe driving pulley 3i to the shaft 33, whereby the bars 27 and 28 aremessie reciprocated, and so Valso the tubular member 38. The arms 35upon the said bars agitate the disks, and cause them to drop into thegroove 15. The reciprocating bars 27 and 28 keep the disks in the grooveby means of their teeth,or projections 36 continuously in motion, a bar,moving toward the reciprocating tubular member 38, feeding a number ofdisks at the stroke toward the tubular member through the dischargeopening 37 into the tubular member 38. It is to be observed that theratio of the worm gear 4:8 and the worm 4.7 is such that even at a-slowspeed of the shaft 33 va vibrating motion will be imparted to thetubular member 38, such vibration causing the disks to move toward theaperture 41 in the side'19 of the casing 19, and through the saidaperture into the tube 50. The crank 4.4. is of such size and the head42 of the tubular member 38 is disposed in such'relation to thedischarge' opening 37 that, in the rotation of the crank, the said headalternately opens and closes the said opening. For this reason the iowof the disks into the tubular member 38 will be intermittent, wherebyclogging of the inlet to the tube will be effectively prevented. Due tothe vibrating motion of the tube 38, the feeding of the disks to thetube 50 will-be positive, and inasmuch as the said tubular member isinclined toward the said tube, the disks will be stacked one on top ofanother within the tube.

Before starting the `operation of the feeding means, the operator bringsthe weighted lever into the position shown in Fig. 2 of the drawings, inwhich its finger 52 projects through the slot 51 into the tube. Thefriction between the ring 55 and the outer face of the tube issuiiicienty to keep the ring in position upon the curved portion of saidy tube. As now the feeding of the disks is started, the weight of thedisks in the tube 5() causes the ring 55 and the weighted lever carriedthereby to move downward until the iiexible connection 56 is drawn taut,whereby the linger 52 is withdrawn from the tube. The disks will thenslide down into the vertical portion of the tube. The weighted leverperforms thus automatically an operation which has heretofore been donein starting the feeding operationmanually, to wit: the insertion andkeeping of a pointed instrument in the tube until a suitable quantity ofdisks has been fed thereinto.
